Our guide to postbiotics

In this article, we continue our article series on the -biotic family members, and this time we take a closer look at the postbiotics. We will go through the purpose and most important functions of using postbiotic substances, as well as discuss whether this group has any positive impact on our overall health and skin.

What is postbiotics

Simply put, postbiotics are substances produced by microorganisms . A slightly more detailed definition shows that postbiotics are a complex mixture of metabolic substances produced by probiotics, e.g. live bacteria and yeast. Postbiotics are generated in a fermentation process where the microorganisms produce various beneficial substances. Postbiotics are also produced naturally in the gut or on the skin.

When it comes to skin care, the most common postbiotic ingredients are substances produced by lactic acid bacteria of the genus Lactobacillus or yeast, mainly from various Saccharomyces species. The substances produced by the microorganisms are collected and separated from the living cells. The postbiotic substances include important vitamins, amino acids, peptides, fatty acids and various polysaccharides.

Why are postbiotics good for our skin and health?

Postbiotics have been shown to have a positive impact on our skin health. In the literature, postbiotics have been reported to have an antioxidative, anti-inflammatory, antiproliferative and immunomodulating effect. In addition, postbiotics promote a more diversified and balanced microbiome.

Historically, postbiotics have been studied more in terms of gut health, but in recent years use on the skin has been studied more thoroughly. As previously mentioned, postbiotics have been shown to have a positive impact on skin health. For example, various bacterial extracts have been shown to be effective in relieving acne and eczema conditions. Other studies have shown that postbiotic ingredients had a positive impact on the skin's repair processes and a soothing effect and counteracted redness as well as an anti-inflammatory and antimicrobial effect. In addition, postbiotics have been shown to improve the skin barrier and accelerate the renewal of the epidermis.

Some postbiotic ingredients are known for their antimicrobial properties and their ability to inhibit various bacteria that may be pathogenic, e.g. Pseudomonas aeruginosa and Staphylococcus aureus. Interestingly, many studies have shown an inhibitory effect against acne-causing bacteria.

Postbiotics in our daily life

The dietary products that naturally increase the postbiotic substances in our body are cottage cheese, fiber-rich foods (oats, seaweed and garlic), fermented products such as pickles, kimchi, kombucha, sauerkraut and yogurt.

When it comes to cosmetics, the majority of postbiotics on the market come from bacteria, most often from lactic acid bacteria of the genus Lactobacillus. The majority of ingredients are various lysates, i.e. parts from dead bacteria and yeasts, and consist of organic acids, polysaccharides, peptides and various compounds from the bacterial and yeast cells. In summary, when looking for postbiotics in skin care products, we suggest looking for ferment or lysate components. A couple of examples are lactobacillus ferment, lactobacillus lysate and Bifidobacterium lysate.


Postbiotics in Skinome's products

In our products there are two types of postbiotic ingredients - Lactobacillus ferment and Lactobacillus (rice ferment).

Lactobacillus ferment

Used in our products to moisturize the skin and prevent the growth of bad bacteria. This ferment is found in our Mineral and Sensitive Cleanser.

Lactobacillus (rice ferment)

A patented postbiotic ingredient that has anti-inflammatory properties, helps bind moisture in the skin, strengthens the skin's immune system and balances the natural skin flora. This ingredient is found in our Light Emulsion.
